Google Docs in the Classroom

I have started using Google Docs in the classroom.  Slowly, I am convincing my teammates to join me in this adventure.  The students are excited but when they go home they often encounter problems.  This combined with a lack of understanding from some parents causes a lot of emails after school hours.  So! I created a How To PDF that I am sending home with students that parents will have to sign.  Hopefully this will solve a lot of problems...It is translated into Spanish, but the I found the translations on Google Translate, so they may not be accurate...
